My research interests include: reconstructing past pH and CO2 of the ocean-atmosphere system, modern and ancient mineral deposits and hydrothermal systems, river water geochemistry and even the use of geochemical techniques to study hip implants. My Dean's position also sees me strongly involved in geochemical education and outreach at high school and university level. I am currently chair of the Nominations Committee of the Geochemical Society.

Non-Officer DirectorsNon-Officer Directors participate in Board discussion and serve on the Board as voting members. This is a four-year term of service. (choose THREE) There must always be at least two North American (NA) directors and two non-North American (NNA) directors on the Board. There are currently three mid-term directors: 2 NNA, 1 NA. For this election, the North American candidate with the most votes shall be elected to fullfil the composition requirments. The remaining two positions will be filled by the two candidates with the most votes, regardless of location. Vickie C. Bennett (NNA)
